EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car is
being driven in severe conditions, more
frequent oil and filter changes are re‐
quired.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu‐
ration and replace if necessary. Drive
belts should be checked periodically for
proper tension and adjusted as neces‐
sary.
CAUTION
When you are inspecting the belt,
place the engine start/stop button in
the OFF or ACC position.
Fuel filter (for diesel)
A clogged filter can limit the speed at
which the vehicle may be driven, dam‐
age the emission system and cause
multiple issues such as hard starting. If
an excessive amount of foreign matter
accumulates in the fuel tank, the filter
may require replacement more fre‐
quently.
After installing a new filter, run the en‐
gine for several minutes, and check for
leaks at the connections. Have the fuel
lines, fuel hoses and connections re‐
placed by a professional workshop. Kia
recommends to visit an authorized Kia
dealer/service partner.
Fuel filter (for gasoline)
Kia gasoline vehicle is equipped a life‐
time fuel filter that integrated with the
fuel tank. Regular maintenance or re‐
placement is not needed but depends
on fuel quality. If there are some im‐
portant safety matters like fuel flow
restriction, surging, loss of power, hard
starting problem etc, fuel filter inspec‐
tion or replace is needed.
Have the fuel filter inspected or re‐
placed by a professional workshop. Kia
recommends to visit an authorized Kia
dealer/service partner.
Fuel lines, fuel hoses and
connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
Have the fuel lines, fuel hoses and con‐
nections replaced by a professional
workshop. Kia recommends to visit an
authorized Kia dealer/service partner.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapor hose or
fuel filler cap is correctly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi‐
dence of heat and/or mechanical dam‐
age. Hard and brittle rubber, cracking,
tears, cuts, abrasions, and excessive
swelling indicate deterioration. Particu‐
lar attention should be paid to examine
those hose surfaces nearest to high
heat sources, such as the exhaust
manifold.
